This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

A hallmark of the phase diagrams of quantum materials is the existence of multiple
electronic ordered states, which, in many cases, are not independent competing phases, but …

Strongly interacting electrons in solid-state systems often display multiple broken
symmetries in the ground state. The interplay between different order parameters can give …

In transition metal compounds, due to the interplay of charge, spin, lattice and orbital
degrees of freedom, many intertwined orders exist with close energies. One of the commonly …

Superconductivity in topological materials has drawn significant interest from the scientific
community as these materials provide a hint of the existence of Majorana fermions …

Nematic superconductivity is a novel class of superconductivity characterized by
spontaneous rotational-symmetry breaking in the superconducting gap amplitude and/or …

Nematic superconductors possess unconventional superconducting order parameters that
spontaneously break rotational symmetry of the underlying crystal. In this work we propose a …

Cu x Bi 2 Se 3 hosts both topological surface states and bulk superconductivity. It has been
identified recently as a topological superconductor (TSC) with an extraordinary nematic, ie …

Quantifying electron-phonon interactions for the surface states of topological materials can
provide key insights into surface-state transport, topological superconductivity, and …

Charge-4 e superconductivity as a novel phase of matter remains elusive so far. Here, we
show that charge-4e phase can arise as a vestigial order above the nematic …
